Saturday i wrote a mail to havells company regarding fake switches.. I got this reply from them.. I am planning to approach them directly.

Sir

I am Unnikrishnan from the Bangalore branch of Havells India Ltd. It is true that there are a lot of duplicate products in the market and to ensure the sanctity of our brand and products we do have many prevalent measures in place to keep a check on the market.

If you can provide us with your requirement , we can discuss further regarding this.

The problem with Panasonic Vision switches is the way the wire is connected. In other switches you have screw terminals but in vision switches it's snap on type, so for the electrician, he has to do more work while looping it from one terminal to other for parallel connection. The quality of switches though is really very good.

Just to add, I am using ABB metal box for Panasonic Vision switches. Advantage is ABB boxes have an option to make the front face plate straight even if the box is not. Another advantage is if the box is slightly coming out of the wall, due to the groove in the wall not being deep enough, there is enough metal before the pins to grind and make it even with the walls.

Panasonic "vision" switches are leagues ahead in engineering design ,appearance and reliability and that too its Japanese. (definitely different from the ones from Anchor Stable). Contrary to what msananthu said , wiring with Vision switches is atleast integer multiple faster than the screw terminal. I have personally verified it by wiring a few , terminal type wiring is a mess. we had over 250 5a switches and sockets installed very quickly . Each switch has 4 terminals 2 for looping all snap on type . (Check the image in the brochure).More than that it is designed for safety , Safety comes from the point that none of the copper or terminals is exposed , after its wired you can run your hand on the backside without the risk of electric shock , once the wire is latched ,also it is not possible to pull out easily unless you operate the latch. The build quality and plastic is very high grade and very rugged . The top cover comes with plastic cover encasing , you can install all the switches before the painting without worrying about the paint or dust getting in.It is slightly expensive costs 68/- Rs per 5A switch , you can get 53% discount on MRP .
